Hip Joint Plan Flashcards
What is the classification of the hip joint?
Synovial ball and socket joint
What cartilage is present in the hip joint and what is its function?
- Hyaline Cartilage
- Reduces friction/shock absorption
What bursa are present in the hip and where are they?
- Trochanteric bursae - sub gluteus medius bursa and subgluteus maximus bursa
- Iliopsoas bursa
- Ischial bursa
Describe the joint capsule at the hip…
- Attached to articular margins
- Tight posteriorly and strengthened by ligaments
What is the function of the synovial membrane at the hip?
- Lines capsule
- secretes synovial fluid (nourishes cartilage, removes waste, reduces friction)
